Product description: Ultrasonic distance sensor 30-500 cm 75 kHz - URM15 - RS485 - with waterproof probe - DFRobot SEN0519
The ultrasonic distance sensor manufactured by DFRobot and equipped with the URM15 system enables the measurement of distances in the range from 30 cm to 500 cm . The measurement resolution is 10 mm and its accuracy is ± 1%. For communication, the sensor uses the RS485 interface based on the standard Modbus-RTU protocol. The sensor is characterized by high measurement precision and maintains stable performance even in complex design conditions.
Ultrasonic distance sensor URM15 ended with a measuring probe.
The product is compatible with Arduino!
The manufacturer has prepared a detailed user guide that makes it much easier to start working with the sensor. You will find there, among others pin description, connection diagram and sample program code - check it!
